World History

1. As industry spread in the Second Industrial Revolution, the British and German governments initiated reforms to improve workers’ lives. What motivated Bismarck to enact reforms in Germany? What kinds of reforms were enacted in Germany and Britain?

Can someone give me information that answers these questions? I'm especially stuck on what motivated Bismarck. My textbook does not make it clear what motivated Bismarck. And trust me, I've read my book MANY times. Nothing different. Please help me!
